Desktop Grade

The MG400 has an all-in-one design that effortlessly fits into a 190 mm x 190 mm space. It is highly portable and is ideal for flexible production.

Industrial Grade

The MG400 is equipped with a servo motor having a high-precision encoder, proprietary drive and controller, to achieve ±0.05 mm repeatability. Vibration suppression algorithm increases multi-joint motion stability time by 60% and reduces residual vibration by 70%.

Simplicity for Usability

With drag-to-teach, the MG400 is designed to be easy to use. The MG400 lowers the barrier of entry into automation and is favored by numerous small and medium enterprises.
